o ICE-CREAM FREEZER.

SPECIFICATION forming part of Lettersi Patent No. 291,685, dated January 8, 1884.

Application filed March 31, 1883. (No model.)

TortZZ whom it may concern:

Be it known that I, VALENTINE CLAD, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Ice-Cream Freezers; and I do hereby declare the following to be a full, clear, and exact description of the invention, `such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the drawings, in which- Figure 1 is a vertical central section of a can constructed according to my invention; Fig. 2 is a detail view.

This invention has relation to thatclass o ice-cream freezers in which is employed a cylindrical metal can adaptedto be oscillated or rotated in a vessel containing ice by grasping in the hands y a handle secured to the lid. Heretofore such cylindrical cans have been constructed of tin or other sheet metal, with a wire` secured to or a bead formed around the upper part or throat, while the lid has been formed with a tin or other sheet-metal rim, also wired or beaded after the usual method of constructing caps for cans. Vhen the cap or lid is iitted on the cylinder, the two are interlocked by suitable corresponding lugs and notches or other equivalent devices. The handle to the cap is commonly formed oi a piece of stout tin bent to the required shape and soldered or riveted to the top of the cap.

My improvements consist in constructing the cylinder with acast-metal ring having a shoulder at its lower edge, and with lugs to fit in recesses in the cap, furthermore, in constructing the lid or cap with a cast-metal rim, also shouldered and having suitable recesses to receive the lugs on the cylinder-rim.

Referring to the accompanying drawings,A designates a cylindrical vessel or can of suitable dimensions, made of tin or other sheetmetal, in the form shown. i

B designates a cast-metal ring, which is tted over the upper part of the cylinder and soldered thereto. This ring is cast with a bead or shoulder at its lower edge, as shown at b, and with a lug, as shown at b.

C designates the lid or cap, of which the crown or top plate, c, is made of sheet metal, While the rim o is a cast-metal ring formed with a bead or shoulder at G2 and having a recess at d to receive the lug b. The crown and rim are secured together by the edges of the former being bent down to embrace the upper edge of the rim to which it is soldered. To strengthen the rim, it may be re-enforced where the notches or recesses are formed by increasing the thickness of ,the metal.

E E designate cast-metal standards, having feet e e, which are soldered and riveted to the crown-plate of the lid, and having eyes or sockets ef e to receive the ends of around wooden handle, el, secured in place by means of screws f, and serving as a convenient non-conducting handle therewith, to manipulate the vessel, and protecting the hands of the operator from `the discomfort usually experienced in handling a piece of intenselycold metal. These standards are tinned to prevent rusting. 'Ihe rings B G are also tinned for the same purpose, and to correspond with the rest of the metal.

The advantages of the cast-metal rings on the cylinder and lid are that the parts are rendered much stronger and more durable than heretofore, while, there being no possibility of the cast metal being bent or battered, the lid will always t truly and be easily attached and displaced.

Ido not claim, broadly, a vessel of tin or sheet metal having a cast-metal rim, as I am aware that this construction has been used on cylindrical vessels; nor do I claim the combination, with the lid and body of an ice-cream freezer, "of cast-metal interlocking lugs, the same being old.

Vhat I claim as myinvention is as follows:

An icecream-freezing vessel comprising a cylindrical body and a corresponding cap or lid, both of sheet metal, and having each a cast-metal rim, one of said rims being formed with a lug integral therewith and the other a corresponding notch adapted to receive said lug and to prevent the lid from turning on the body, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 28th day of March, A. D. 1883.
